Yeah other Rogue getting stuck there wasn't one moment in any of the films where I felt Wolverine was feral and his allies were in danger from his rage. The mansion raid showed how mean he could be and it was a good sequence. But he was never berserker and that is the element missing from his character.

Envision a feral Wolverine skulking out of the dark and advancing on a terrified Jean. The animal roars and charges in for the kill just as Jean lashes out in desperation. The shock restores Logan's senses and he recoils realizing what he's done.
